Nowadays, free-form surfaces have been widely used in various industrial fields. They are
usually machined by CNC machine tools, but recently have also begun to be manufactured …

With the rapid development of aerospace, energy, and power technologies, the demand for
high-performance parts with complex curved surface is increasingly large, and the multi-axis …

Nonlinear and configuration-dependent five-axis kinematics make contouring errors difficult
to estimate and control in real time. This paper proposes a generalized method for the on …

This paper presents a general solution of precise position synchronous control for multi-axis
servo systems. The control strategy to achieve high-precision motion is summarized in two …

The PID control system is widely used for industrial machine control processes. The success
of PID control is determined by tuning PID parameters. In PID control the tuning is carried out …

When the trajectory with high speed and high acceleration contains frequency contents
matching with the structure mode, the inertial vibration of the structure is easily excited …

The five-axis machine tool and industrial robot are two important systems in modern
manufacturing systems. For accurate machining, the contouring control of these systems is …

Contouring error is one of the most important performance indexes for multi-axis motion
systems, especially for five-axis ones. The contouring control performance of five-axis …

Methods for pre-compensating contour errors in servo systems by adding components of the
predicted contour error to the reference position command have recently been proposed in …

This paper presents several novel methods that improve the current input shaping
techniques for vibration suppression for multi-degree of freedom industrial robots. Three …
